Jam drops are classic Australian cookies with a buttery and crumbly texture. These delicious treats are made by combining butter, sugar, flour, and vanilla extract to create a dough. The dough is then rolled into small balls and pressed with your thumb to create an indentation. A dollop of your favorite jam is added to the center of each cookie before baking. The result is a sweet and fruity cookie that is perfect for afternoon tea or as a lunchbox treat.
